as a result of the New York City Tax Appeals Tribunal (the "Tax Tribunal") decision in 2018. We appealed the Tax Tribunal's decision to the New York State Supreme Court, Appellate Division, First Department ("Appellate Division"). The Appellate Division entered a unanimous decision and order that confirmed the decision of the Tax Tribunal and dismissed our appeal. We filed a motion to reargue the Appellate Division's decision or for leave to appeal to the New York State Court of Appeals. That motion was denied in December 2019 and can no longer be appealed.</span></div>
